"We don't have all the results yet but we're giving you what we have so far on the new iMac G5s (2.1GHz and 1.9GHz) compared to the previous model (2.0GHz). I hypothesized that we'd see small gains in CPU intensive tasks and big gains in graphics intensive tasks. I noticed in various discussion groups that many consumers are trying to decide between the high end iMac and low end Power Mac. So I included the results from the Dual-Core G5/2.0GHz Power Mac."
